On stackoverflow.com there seems to be a problem with displaying the number of question tagged with windows. If I type [windows] in the search box or click on the windows tag under a question tagged with windows only two questions are returned. On the other hand if I go to tags and in Type to find tags: enter windows I get this: again clicking on windows shows only two questions.
Why are these numbers inconsistent? This seems like a bug. I see some examples of questions tagged with windows that are not showing here.

EDIT: thanks to AnnaLear's comment: in fact clicking on stackoverflow.com/questions/tagged/windows leads to the featured tab. Again this seems like a bug.

@izomorphius It's occasionally confusing, but that's how tabs work. The last one you visit persists. For you it took you to Featured. For me, it went to Newest. Try it out - go to the Newest tab for windows and then visit a different tag.

you are right. That was the problem and it is confusing.
